Step-by-step explanation:
Question :-
Find the zeros of the polynomial 3x²+x-2
Required Answer :-
2/3 and -1 are the zeroes of the polynomial 3x² + x - 2
By Splitting the middle term :-
3 {x}^{2} + x - 23x
2
+x−2
{3x}^{2} + 3x - 2x - 23x
2
+3x−2x−2
3x(x + 1) - 2(x + 1)3x(x+1)−2(x+1)
(3x - 2)(x + 1)(3x−2)(x+1)
To find the zeroes we will equate this to zero.
1. \: 3x - 2 = 01.3x−2=0
3x = 23x=2
x = \frac{2}{3}x=

2. \: x + 1 = 02.x+1=0
x = - 1x=−1
Therefore the two zeroes are 2/3 and -
